More about Karmen Ransomware

Karmen Ransomware is a kind of Ransomware which uses HiddenTear source code to hack your computer. It belongs to Mordor Ransomware family. Once it hacks a computer, it will append .grt file extension to the encrypted data. Then, it uses AES encryption way to block those files. This malicious Ransomware also encrypt victims’ files and has a good concealing performance, which increase the difficulty of detection. Unlike other ransomware, Hades Karmen Ransomware uses symmetric cryptography (encryption and decryption use the same key). And cyber hackers store the secret key in remote servers.

Files encrypted

All files are encrypted! Please follow the mind. In order to get the key to decrypt send this amount to our wallet Bitcoin.
Decrypt files automatically.
Interference with the program – can leave you without files.

 

 

If I were you, I wouldn’t make the payment. The reasons are chiefly as follows.

  1. Unreliability of the ransom note. It is not sure whether cyber criminals will keep their promises after you have paid for decryption key. Cyber criminals won’t provide their real information to contact. Hence, you won’t get your money back if it is actually a fraud.
  2. Unsafety of payment links. Without protection of antivirus program, you’d not better click strange links, which may result in financial data leakage. Following the instructions provided by cyber hackers means giving a chance for them to steal your personal information.

 

How Does Karmen Ransomware Enter Your PC?

 

In addition to spam emails, exploit kits (Eks) are also one of most popular used distribution techniques. According to the research, Neutrino, Magnitude and the RIG Exploit kit have become major “accomplices” of spreading Karmen Ransomware. As shown, a cyber hacker will attract computer users to click a link or website, which can access exploit kits. After finding system vulnerabilities, an exploit kit will deliver a payload ( a part of malware) to your system. And then the malware begins to conduct malicious activities on the PC. A malvertisement (malicious advertiesemnt, fake software update message or lottery winnings) is another “accomplice” that helps hackers to spread malware. So, you should be more careful when you are browsing the Internet and downloading software.
